Advantages
Compared with centrifugal pump with mechanical seal or packing seal, magnetic pump has the following advantages.
1.
Stainless steel magnetic pump shaft from the dynamic seal into a closed static seal, completely avoiding the leakage of media.
2.
Without independent lubrication and cooling water, energy consumption is reduced.
3.
When overload, the internal and external magnetic rotor relative slippage, to the motor, pump protection.
Magnetic pump is a kind of magnetic drive (magnetic coupling) to achieve non-contact torque transmission so that static seal instead of dynamic seal, so that the pump to achieve complete non-leakage.
Because of the pump body, pump shaft, the magnetic rotor of sleeve completely closed, so as to thoroughly solve the “run, run, drip, leak problem, eliminates the oil refining chemical industry flammable, explosive, toxic and harmful medium by pump seal leakage of safe hidden trouble, effectively guarantee the staff’s physical and mental health and safety in production.

2.

3.
From coupling drive to synchronous drive, there is no contact and friction.
Low power consumption, high efficiency, and damping to reduce the impact of motor vibration on pump and pump cavitation vibration on motor.
4.
When overload, the internal and external magnetic rotor relative slippage, to the motor, pump protection.
When the driven parts of the magnetic actuator run under overload or the rotor is stuck, the main and driven parts of the magnetic actuator will slip off automatically and protect the pump.
At this point, the permanent magnet on the magnetic drive will generate vortex loss and magnetic loss under the action of the alternating magnetic field of the active rotor, causing the temperature of the permanent magnet to increase and the slip failure of the magnetic drive.
